I've always felt kind of meh about The Grateful Dead, as both performers and songwriters. Somehow neither loving nor hating them feels like a character flaw. But I _adore_ Norma Waterson's cover of Black Muddy River: https://www.whosampled.com/cover/516817/Norma-Waterson-Black-Muddy-River-Grateful-Dead-Black-Muddy-River/ [the rest of the album is great too, but this is the song on it that can get stuck in my head from hearing 5 seconds of someone else's version of the song, and one of those earworms I'm always happy to have]
